Review of Regional Weather and Smoke Haze
Some pockets of dry weather have started to develop over northern and central Sumatra and over a larger part of the northern half of Borneo in January as the northeast monsoon rain-belt progresses further south of the Equator over Southern Sumatra and Java island. The number of hot spots, however, was small on most days.

Weather and Haze Outlook

(Meteorological Service of Singapore 10 July 2002)

"The inflow of Southwest Monsoon winds has heralded the onset of the traditionally dry season in the region. With the continued expectation of a weak El Nino in the second half of the year, increased occurrences of forest fires and smoke haze can be expected over Indonesia and Kalimantan in the coming few months. At this stage, while periodic haze can be expected, the chance of a recurrence of the 1997-type severe prolonged widespread smoke episode is assessed to be low."

The ASEAN Fire Weather Information System (ASFWIS) is a co-operation between ASEAN and the Canadian Forest Service. It provides maps describing the current fire weather situation in South East Asia. This system is based upon the Canadian Forest Fire Danger Rating System (CFFDRS) (for further infomation to the CFFDRS refer to ASFWIS). Studies have shown that the CFFDRS is applicable outside of Canada. Currently it is also used in a modified form in New Zealand (see References). In New Zealand the Fire Weather Indices Fine Fuel Moisture Code (FFMC) and the Initial Spread Index (ISI) represent the fire danger in the scrublands. The Duff Moisture Code (DMC) is also applicable in South East Asia, because it potentially describes the moisture state of the upper peat layers in peat and peat swamp forests. All three parameters may serve as a suitable indicator of forest fire danger in South East Asia.

The updated ASFWIS maps show fire weather, fuel conditions and fire behaviour parameters for South East Asia:

South East Asia Fire Monitoring by ANDES
The Asia Pacific Network for Disaster Mitigation using Earth Observation Satellite (ANDES) provides daily fire maps of mainland and insular South East Asia. The latest maps can be accessed through the ANDES website. The map below shows the latest fire map of mainland SE Asia (Thailand, Myanmar, Lao, Cambodia, Viet Nam).

The Forest Fire Prevention and Control Project (FFPCP) 
The Forest Fire Prevention and Control Project (FFPCP) in Palembang (Sumatra) closed on 30 November 2001. The South Sumatra Forest Fire Management Project (SSFFMP) is expected to start within the second half of the year 2002 and will continue the work of FFPCP.
Meanwhile the daily fire map (hot-spot) and monthly drought index for Sumatra will continue to be updated from time to time.

Haze Prevention Group
The industrial initiative to combat haze in SE Asia provides a website which includes information about the objectives of this industrial initiative and projects implemented to reduce wildfires and haze in Indonesia.

 

The ASEAN Haze Action Online provides the following information:

 

The Integrated Forest Fire Management Project (IFFM) in Samarinda provides regulary updated  hot spots maps of Kalimantan.
